摘要： In a data processor for updating path metrics in Viterbi decoding, an ACS processing can be efficiently executed with small power consumption. An ACS processing unit obtains an updated path metric through an ACS processing on the basis of pre-update path metrics read from a memory. In the memory, two pre-update path metrics necessary for obtaining one updated path metric are stored in an even address and an odd address having common bits excluding the least significant bits, so that the two pre-update path metrics can be read through one access. In the first cycle, the ACS processing unit makes an access to the memory and obtains a first updated path metric through the ACS processing on the basis of the thus read two pre-update path metrics. In the second cycle, without making any access to the memory, the ACS processing unit obtains a second updated path metric through the ACS processing on the basis of the two pre-update path metrics read in the first cycle.

摘要： A coding apparatus includes shift register, input register and logical operation section. The shift register performs bit shifting on an input bit sequence and stores one bit of the input bit sequence after another. The input register stores coefficients of terms on respective orders of a generator polynomial. The logical operation section obtains logical products of the respective bits stored on the shift register and associated bits stored on the input register and a logical product of each one bit input to the shift register and an associated bit stored on the input register so that the earlier a bit of the input bit sequence was input, the higher-order one of the coefficients in the terms of the polynomial the input bit is associated with. Next, the logical operation section derives an exclusive logical sum of the products and then outputs the sum as a bit of a code sequence.

摘要： A method of operating a digital signal processor is provided. The digital signal processor may be provided as a radio communication mobile station, a radio communication base station apparatus, or a CDMA radio communication system. Each path metric PM1 and PM0 of an old state is added to each branch metric BM1 and BM0 separately. A path metric of a new state N is formed by comparing the value of PM1+BM1 to the value of PM0+BM0. A path metric of a new state N+2k−2 is formed by comparing the value of PM1+BM0 to PM0+BM1.

摘要： A memory device including a first memory and a second memory. A first processor generates a first address for defining a location to be accessed in the first memory and a second address for defining a location to be accessed in the second memory. A second processor generates a third address. A memory control section controls access to the first memory and access to the second memory. The memory control section includes an address conversion section for converting the third address so as to represent either one of the first address and the second address.

摘要： Excess sludge production in a bioreactor of a wastewater treatment plant in which excess sludge is being produced is reduced by adding an activated sludge material having a chitinase specific activity of at least 150 Units/g-MLSS and a pectinase specific activity of at least 120 Units/g-MLSS to the bioreactor. After the addition of the activated sludge material, the bioreactor is controlled by adding the activated sludge material when any one of the chitinase activity, the pectinase activity, and the protease specific of the sludge in the bioreactor drops below the lower limits of 50 Units/L, 40 Units/L, and 0.3 Units/L, respectively.
